For the first time, a study of potentially significant polymorphisms of the LIF (rs322167972), NCOA1 (rs335362002, rs697739229) and BF (rs339261793) genes was carried out on a sample of Landrace and Yorkshire sows of Belarusian selection. Primers were designed to identify the polymorphisms under study. Using proven methods, a sample of pigs (n = 147) was genotyped, and the frequencies of alleles and genotypes were determined. It was shown that the number of born and born live piglets from sows with the LIFBB genotype of the Landrace breed exceeded by 1.0 goals animals with the LIFAA genotype (p < 0.05). Nest weight at birth was significantly higher in Landrace animals with the LIFAB/BB genotype compared to animals with the LIFAA genotype by 0.9 kg (p = 0.017). Animals with the LIFAA/AB genotype were significantly superior to animals with the LIFВB genotype in live weight of the nest at 21 days by 3.685 kg (p = 0.018). A similar trend was observed in Yorkshire animals, but the differences were not statistically significant. A tendency was shown that the live weight of the nest at 21 days was higher in Landrace animals with the BFBB genotype compared to animals with the BFAA/AB genotype by 2.28 kg (p = 0.054).
